b.box | Weighted Straw Sippy Cup

The b.box Weighted Straw Sippy Cup features a clever weighted silicone straw that moves with the liquid, enabling kids to drink from any angle—even upside down. Its unique two-way valve ensures smooth flow without leaks, suitable for warm or cold liquids. Designed with flexible, soft silicone for baby comfort, the cup includes easy-grip handles promoting independent drinking. A flip-top lid keeps the straw clean, while measurements on the base help track hydration. Compatible with training and spout lids, and supported by a replacement straw and cleaner set, this cup offers lasting value and hygiene.
